Why is the last frame my photoshop made gif white ?

[juste39434415]

Everytime I try making a gif from a video, I follow the official adobe tutorial... yet I always get a white last frime before it loops, like so ; https://imgur.com/a/PcV27

How to remove that ? I can't seem to see where the problem is... Thank you !

Would you mind posting a screenshot of your frame timeline?

My guess is that your frames end at different times.

My first example is a gif that I made with the frames ending at different times

This second gif is with the frames ending at the same time

Thank you so much for your answer and please excuse my belated answer 

Here is the file of the gif shown ; https://mega.nz/#!FEF2BCqS!acQkIKoENjwWT45QTMCan8It-QGgcQfRp41Z58ER9F0

My timeline doesn't quite look like yours so I thought it better to just hand out the file.

Thank you so so much for your help !

Looks like all of your layers in your timeline were longer than the animation itself.

I was able to fix this by shorting the length of each frame

Thank you so much for correcting it ! Would you mind explaining how you fixed it in detail ? How to modify the length of a gif ? If I ever wanted to keep that amount of layers but wanted a slowmo effect for exemple, would I be able to lengthen it ?

You could lengthen the overall time of a gif by slowing the gif down.

I changed the length of the gif by simply dragging each clip down by 1 second.

Thank you so much for your help ! Hopefully I'll be able to make proper gifs on my own now !
